nClimGrid Historical Observations Energy Indicators
收藏资源简介:
The Climate Resilience Information System (CRIS) provides data and tools for developers of climate services. This layer has historical variables in decadal increments from 1950 to 2020 derived from historical observations of air temperature and precipitation. The variables included are: Cooling degree (F) days Heating degree (F) days This layer uses data from the NOAA Monthly U.S. Climate Gridded Dataset (nClimGrid). Further processing by Esri is explained below. For each variable, there are mean values for the defined respective geography: counties, tribal areas, HUC-8 watersheds. The process for deriving these summaries is available from the CRIS Website’s About the Data. Other climate variables are available from the CRIS Data page. Additional geographies, including Alaska, Hawai’i and Puerto Rico will be made available in the future. Geographies This layer provides historic values for three geographies: county, tribal area, and HUC-8 watersheds. County: based on the U.S. Census TIGER/Line 2022 distribution. Tribal areas: based on the U.S. Census American Indian/Alaska Native/Native Hawaiian Area dataset 2022 distribution. This dataset includes federal- and state-recognized statistical areas. HUC-8 watershed: based on the USGS Washed Boundary Dataset, part of the National Hydrography Database Plus High Resolution. Time Ranges Historic climate threshold values (e.g. Days Over 90°F) were calculated for each year from 1950 to 2020. To ensure the layer displays time correctly, under 'Map properties' set Time zone to 'Universal Coordinated Time (UTC)' and under 'Time slider options' set Time intervals to '1 Decade'.

气候韧性信息系统(Climate Resilience Information System,CRIS)为气候服务开发人员提供数据与工具套件。本图层包含1950年至2020年间以十年为步长的历史变量数据,这些数据源自气温与降水的历史观测记录。所纳入的变量包括:冷度日(Cooling degree days)、取暖度日(Heating degree days),单位均为华氏度(F)。本图层采用的数据来自美国国家海洋和大气管理局(National Oceanic and Atmospheric Administration,NOAA)月度美国气候网格化数据集(nClimGrid)。Esri公司的后续处理步骤将在下文中说明。针对每个变量,本图层提供了预设地理区域的平均值,涵盖县级行政区、部落辖区以及8位水文单元流域(HUC-8)。上述汇总数据的生成流程可从CRIS官网的「数据说明」板块获取。其他气候变量可通过CRIS数据页面获取。未来将新增包含阿拉斯加、夏威夷及波多黎各在内的更多地理区域图层。 地理区域 本图层提供三类地理区域的历史数值:县级行政区、部落辖区以及8位水文单元流域(HUC-8)。县级行政区:基于美国人口普查局2022版TIGER/Line矢量数据集制作。部落辖区:基于美国人口普查局2022版《美国印第安人/阿拉斯加原住民/夏威夷原住民区域数据集》制作,该数据集包含联邦与州政府认定的统计区域。8位水文单元流域(HUC-8):依托美国地质调查局(USGS)的冲刷边界数据集(Washed Boundary Dataset)制作,该数据集隶属于国家高精度水文数据库增强版(National Hydrography Database Plus High Resolution)。 时间范围 本图层针对1950年至2020年的每一年计算了历史气候阈值(例如:高温日数,即日最高气温超过90华氏度的天数)。为确保图层时间显示正确,请在「地图属性」中将时区设置为「协调世界时(Universal Coordinated Time,UTC)」,并在「时间滑块选项」中将时间间隔设置为「10年」。 数据引用 拉塞尔·S·沃斯(Russell S.
